As far as engine-less tools go, nothing cuts wood across the grain as quickly and efficiently as a sharp handsaw. But no matter if that saw is a bow saw, bucksaw, or pruning saw, those sharp teeth can take a bite out of the sawyer, too. And there’s not likely to be a doctor out there in the woods when you saw your finger off. Use your saw with care, and like any other tool, keep it maintained so that it’s always sharp and useful. These steps should keep your saw in top form.
